Multiply 3 1/2 by two because the distance was hiked twice, then add 2 3/8.
=(3 1/2 * 2) + 2 3/8
=7 + 2 3/8
=9 3/8 miles hiked total
ANSWER: 9 3/8 miles

Answer:
4 teachers for 28 students
Step-by-step explanation:
28/7 = 4
Let’s make x = # of nickels. Then 3x = # of dimes and 3x+6 = # of pennies. A nickel is 5 cents, a dime is 10 cents and a penny is 1 cent.
The money she has should be .05(x) + .10(3x) + .01(3x+6) = 4.62 or to make it simpler: 5(x) + 10(3x) + 1(3x+6) = 462.
5x + 30x + 3x + 6 = 462
38x + 6 = 462
38x = 456
x = 12.
So she has 12 nickels (12 * $0.05 = $0.60), 36 dimes (36 * $0.10 = $3.60) and 42 pennies (42 * $0.01 = $0.42). $3.60 + $0.60 + $0.42 = $4.62.
Can you send a picture of the graph? there's no way to know the answer if we can't see the graph
